In Terra Invicta, humanity faces an unprecedented challenge as an alien probe is detected approaching Earth. Unknown to the world, an alien force has already begun preparations for an invasion from the distant Kuiper Belt. As Earth's nations struggle to unite against this threat, various transnational groups of political, military, and scientific leaders form secret alliances to respond. These factions, driven by different motivations such as hope, fear, or greed, each have their own approach to the alien arrival.
